Heda Margolius Kovály (1919–2010), a Czech writer and translator, was born in Prague to Jewish parents. Heda spent the years of the Second World War in a ghetto, Auschwitz and other concentration camps, escaped from a death march, and took part in the Prague uprising against the Nazis in May 1945. After the war Heda worked at various Prague publishing houses as a graphic designer. In 1952, her first husband, Rudolf Margolius (1913–1952), was convicted in the Stalinist Slánský Trial. The 1968 Soviet occupation of Czechoslovakia forced Heda into exile in the United States. She translated over two dozen books and her celebrated memoir, Under a Cruel Star, was first published in 1973 and has since been translated into many languages. Her crime novel Innocence appeared in Czech in 1985 and in English in 2015. Heda returned to Prague in 1996 where she died.
